My in-laws have a dog that I'm severely allergic to. I can only last about 2 hours before my asthma gets dangerously bad. Don't want to spend the money for a hepa air purifier that will clean the air throughout the whole house. Using the mask I'm able to stay as long as I "want" to stay. It works!!!!

Customer Q & A

Q1: what mask is best to filter out smoke? I am a heart patient who uses public transportation. Smoke from smokers, fires or exhaust causes immediate cardiac symptoms. Thanks

A: The best is going to be this 6291 with the MultiGas or Organic Vapor filters. These masks seal better than most others and there is more odor/smoke adsorbing carbon in the filter cartridges than other masks. Typically though, I recommend start with the least restrictive and mask and work from there. For nuisance level smoke and odors, while traveling, out in the open or driving not for something like sitting in a smoky bar or by a campfire, the Honeycomb Carbon mask is a good fit for most. It's less expensive and the carbon in the filter does a good job with nuisance level smoke/odors and pollutants. Some people will even double the filters up for more robust filtration without losing the slim fit of this mask. The Respro Techno also does a decent job on smoke and odors. The Vogmask then RZ are the least robust of our offering, in terms of removing smoke/odors/chemical vapors. Still, if the look of the 6291 isn't a concern, then opt for it with a set of cartridges for the best filtration of these pollutants. Hope that helps!

Q2: I have a severe anaphylactic seafood/shellfish allergy. I even react to aerosolized particles that are present in the air, especially when seafood is cooked or hot. Is there a filter I could use while flying that would prevent a reaction?

A: You could try this mask or if you want to try a less expensive option but one that will provide the same filtration, opt for the 3M 8293. It is HEPA rated, like this 6291, and the 8293 works with oil based particulate 8233 does not, so it adds a little extra protection. Hope that helps!

Q3: which product is best for airborne gluten hypersensitivity especially the dust and fumes of cooked goods. I have to fly quite often and need the best protection possible with the most breathability while in-flight. Cause you

A: The 3M 8233 is probably your best bet. It's easy to take with you than the 6291 but offers HEPA filtration of particles. Odors are going to be another matter. To remove the particles that often make up odors, activated carbon is best, but if you go with a carbon mask, you'll give up particle filtration. The 6291 has organic vapor and multigas cartridges but when using these, the particle filtration is nowhere near as robust. HEPA filtration will capture some of the particles that make up odors and fumes, but certain elements cannot be filtered by physical methods HEPA. A mask like a N99 Vogmask might also be an option. Instead of HEPA filtration P100, the Vogmasks offers N99 very similar but does have a thin layer of activated carbon for odor adsorption. Hope that helps!

3M HEPA Respirator Review

3M 6291 HEPA Mask

The 3M 6291 HEPA Mask is one my favorite face masks. Unlike disposable masks, the 6291 is durable and can be used repeatedly. I have owned this mask for a several years, and have changed the HEPA filter cartridges twice. I use this mask for just about everything from yard work to more heavy duty projects like like replacing the grout in our shower. Depending on usage, you may have to replace the filters more often, so this will vary depending on use. After several years of service, this my assessment of the 6291 respirator.

What I like about the 3M 6291 HEPA Mask
  • Offers HEPA quality filtration of oil and non-oil based particles
  • Versatile filtration ideal for a wide range of uses from pollen and mold particles while raking leaves to filtering oil based particles you might encounter while staining or working with wood or fiberglass while renovating or working on your home
  • Creates a very tight seal
  • It is durable and easy to clean after dirty projects - rinse respirator itself with warm water or with a mild detergent (filters NOT washable)
  • Fits very snugly with two straps and is fully adjustable
  • Latex free
  • Two sizes available
  • MultiGas or Organic Vapor cartridges optional
  • Made in the USA
What I did not like about the 3M 6291 HEPA Mask
  • As with any tight sealing mask, in warm conditions it will make the area around my mouth sweat, so some moisture will get trapped inside

In all, the 3M 6291 HEPA Mask is the best masks we offer. With NIOSH P100 filtration, this respirator is one of the most versatile available today. It is completely sealed, non latex, HEPA grade, and you can replace the filters when necessary. If you, have allergies, do a lot of yard work, work in a shop or in places where things toxic and non-toxic particles are a concern, I strongly suggest using this mask. The filtration this mask provides also exceeds the CDC's recommended filtration level (N95) to help prevent the spread of the influenza virus. Aside from it being a little warm with extended use or in warm conditions, there is very little not to like about this durable HEPA respirator.
